The “leaked” eShop music for the switch was never meant for the eShop.

I keep on seeing people say about how there was leaked music for the Switch eShop but that isn't true, dataminers couldn't find it in the files and I found out that it's from a few support videos Nintendo has on YouTube for Nintendo Switch. This is probably common knowledge by now but I just wanted to point it out. I attached a link to a support video which uses the song.
